feat: point AI agents at the skill from --help and init

[angeloashmore]

Resolves: N/A

Description

An agent that runs npx prismic --help or prismic init gets no pointer to the Prismic skill. It falls back to training data instead.

Add a hint to two places:

• The root --help description.
• prismic init success output, both the starter-handoff branch and the plain-init branch.

The hint points only to the skill: "Using an AI agent? Teach it how to use Prismic by installing the Prismic skill: npx skills add --global --yes prismicio/skills". --yes skips the confirmation prompts, so an agent can run the command without hanging.

The line lives in one place, AI_AGENT_HINT in src/lib/ai.ts.

No skill detection is added. The hint always shows, for simplicity.

How to QA

Run npx prismic --help and check the description includes the AI-agent hint. Run prismic init against a repo and check the success output includes the same hint.

Please shorten the hint. Drop the docs list pointer and point only to the skill. The skill tells the agent what to do, including where the docs are. Use this one line in both the root --help description and the init output:

Using an AI agent? Teach it how to use Prismic by installing the Prismic skill: npx skills add --global prismicio/skills

Done in 20eae12. Both the root --help description and init output now use the shortened line, no docs list pointer.

One small change: add --yes to the install command, so it reads npx skills add --global --yes prismicio/skills. It skips the confirmation prompts so an agent can run the command without hanging. It still installs to every detected agent. This matches the Prismic CLI docs.

Done in ddd8391. Both spots use npx skills add --global --yes prismicio/skills through the shared AI_AGENT_HINT constant.
